You do not have to have a ball joint stud remover unless you want to save the boots. A Pickle fork will work but the boots usually get torn.
The bushings can be removed with a hammer and chisel & or a small grinder.
To install the bushings you can us a press. For the uppers you can use a jack screw setup also.
That is what you can get away with but I suggest you get these tools.
This tool makes installing & Removing Upper Bushings easier and it can be used for U-joints also.

I do not recommend a particular manufacturer or reseller of those tools I just grabbed them from a google search.
